I'm confused, to what "countless genocides and systems of torture" are you referring?
I will acknowledge that there have been genocides and tortures against practically every group of humans in the past, but I don't see how that is relevant.
I’m guessing they’re talking about things like factory farming, habitat destruction, hunting to extinction, etc. Genocide is the wrong word there and probably responsible for the downvotes, but “systems of torture” is depressingly accurate.
